NUT-LOCK.
Specication of Letters Patent.
Patented June 22, v1909.
Application filed August 22, 1908. Serial No. 449,800.
T 0 all whom t may concern.'
i Be it known that I, EDWIN M. IiovnLL, a citizen ofthe United States, and a resident of Stanberry, in the county of Gentry and State of Missouri, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.
My invention is an improvement in nut locks, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.
Referring to the drawings forming a part hereof, Figure l is a view of a portion ol a pair of abutting rails provided with my improvement. Fig. 2 is a section on the line 2-2 of Fig. l. Fig. 3 is a perspective view of a portion of the lock and Fig. 4 is a similar view of another portion.
The present embodiment of my invention comprises a washer A, substantiallv rectangular in shape, and provided at its center' with an aperture a for receiving the bolt C. The washer is also provided with a circular depression a coaxial with the opening a for receiving the washer B to be presently described. A portion of the top ol" the washer is cut away to form a lug a2, and the lug is provided with an opening a3 polygonal in cross section therethrough, within which is received a sliding bar ai ol similar cross section, having its inner end rounded and pro vided with a head a5, and a coil spring a, is arranged between the head and the washer. The opposite end ol' the sliding bar a4, is bent downwardly as at a7, and inwardly as at as, the free end thereof being beveled as at a and extending within the circumference ol" the circular depression as clearly shown in Fig. 3, the washer being cut away as at al to permit the passage ot the portion as ol' the bar.
The washer B before mentioned, is provided on its periphery with a plurality of ratchet teeth o, and at its center with an aperture b/ for receiving the bolt C. On one ot' its faces, the washer is provided with an integral casing or socket b2 rectangular in cross section, for receiving the nut c as shown in Figs. l and 2.
The device is shown applied for securingl rails together7 the rails D, D', being placed in abutting relation, and connected by Afish plates E, E The bolt C is inserted through the registering openings of the 'fish plates and the rails, and the washer A is placed thereon. It will be observed that the washer A is ol sullicient size so that the upper edge engages the under surface of the tread of the rail while the lower edge engages the upper surface of the ilange of the rail, or the upper surface oll the lish plate, when an angular plate is made use ol', this arrangement pre venting the rotation ol the washer A. rlhe nut is now placed in the socket and the washer B is turned until it occupies the position shown in Figs. l and 2, the sliding bar a being in the position shown in Figs. 1 and 3.
It will be evident l'roin the description, that a reverse movement ol the washer Ii, is prevented by the engagement ol the portion a* with the ratchet teeth, the said portion l'orming a catch or pawl lor cooperating with the ratchet teeth.
Then vlor any reason the nut becomes loose, it may )e tightened merely by applying a wrench to the socket and turning the washer I3. Then it is desired. to release the nut, the pawl is ,moved to the left ol Fig. l, until the catch u,S is disengaged l'rom the ratchet teeth.
It will be observed that the slide bar a* is square, and that the passage a in the washer A is also square, to prevent turning ol the sliding bar, unless the said bar is moved to the lelt lar enough to disengage the squared portion ol the bar Vfrom the socket alter which the sliding bar may be turned to retain it in its outward position.
I claim:
1. A nut lock comprising a washer provided with a central aperture l'or receiving the bolt, and with a circular depression coaxial with the aperture, said washer havingI a lug provided with a passage polygonal in cross section, a slide bar movable in the passage, and also polygonal in cross section, the inner end ol the bar being provided with a head, and the outer end with a catch normally extending within the circumference oll the circular depression, a spring arranged between the head and the lug, and a second washer arranged to `lit within the circular depression, and provided on its periphery with ratchet teeth l'or engagement by the catch, said washer having a central aperture for receiving the bolt, and a socket on its lace lor receiving the nut.
2. A nut lock comprising a washer having an aperture vl'or receiving the bolt, and a circular depression coaxial with the aperture, a second washer provided on its periphery With ratchet teeth, and fitting Within the cirnamed Washer being provided on its face cular depression7 said Washer having a cen- With a socket for receiving the nut, and on tral aperture for receiving the bolt, and a its peripheral edge With ratchet teeth, and a socket for receiving the nut, and a slidable slidable spring actuated catch on the first 5 spring actuated catch on the irst Washer for named Washer for engaging the teeth to lock 1C engaging the ratchet teeth. the Washers With respect to each other.
3. A nut lock comprising a pair of Washers, EDIN M. LOVELL. each having an aperture 'for receiving the TWitnesses:
bolt, one of said Washers being substantially l R. S. LIGGETT, 10 rectangular and the other circular7 the last l A. C. FRISBIE.
